Patented Oct. 6, 1914.

Application filed September 26, 1813. Serial No. 792,028.

To all whom it may concern:

Be it known that I, GEORGE A. SMITH, residing at South Hill, in thecounty of Meeklenburg and State of Virginia,have invented certain newand useful Improvements in Throw-Off Devices, of which the following isa specification.

My present invention has for its objectto provide an improved throw ofidevice for use on board assorting machines of the kind disclosed in myco-pending application filed June 14,1913, Serial No. 773,685. Ininachines of the present type, the boards of various sizes, are movedalong a given path by a conveyer, there being instrumentalities providedat intervals for ejecting the boards of predetermined sizes atpredetermined places, and my present invention provides what I considerto be a more practicable and eiiicient construction of throw offdevices.

than those disclosed in my application above mentioned.

In its general construction, the present invention provides a standardor support, between which and thefence of the machine, the boards arecarried by the conveyer. The standard supports an adjustable rollerbracket which carries a roller and a vertically yieldable guardtherefor. The standard also adjustably supports a shoe to cooperate withthe spring finger that isvertically yieldably mounted on an auxiliarystandard which is adjustably held by a clamp which is itself adjustablysecured to the primary standard, the boards passing between the roller,the guard, and shoe on one side, and the throw off finger on the otherside, the parts being so relatively adjusted that boards of apredetermined size will be thrown out by the spring finger after leavingthe shoe, while boards of a lesser size will pass beneath the shoe andspring finger without being affected thereby, and boards of greater sizewill be held from ejection by the guard that is arranged adjacent to theroller.

More subordinately the invention includes those novel details ofconstruction, combination and arrangement of parts, which will all befirst fully described, and then be specifically pointed out in theappended claims, reference being had to the accompanying drawing, inwhich Figure 1 is a perspective view of a portion of a selectiveassorting machine with my improvements applied. Fig. 2 is a detailperspective view of one of the throw off devices.

1 1g. 3 is a detail sectlon on the line 33 of Fig. 1. Figs. L and are.horizontal sections on the lines H and 5-5 respectively, of Fig. 3,illustrating the manner in which the throw ofi finger operates, and Fig.6 is a view similar to Fig. 5 showing the throw ofi finger as ejecting aboard that has just passed the shoe. Fig. 7 is a detail side elevationof the parts to the left of the line 7-7 in Fig. 8. Fig. 8 is a detailhorizontal section on the lineS-S of Fig. 7.

l designates the fence of the machine which is mounted on a table 2,that has runways orchannels 12 in which the conveyer chains 4 ride, thechains 1 havingpushers 5 for engaging the boards B and moving themalongedgewise in a continuous longitudinal procession.

l0 designates the main or primary standard of tl1e:lil1IO\V oif devicewhich is verti cally adjustable in a clamp member 11, that is bolted orotherwise secured to the underside of the channel-way 12.

9 is an adjustable bracket clamp mounted on the standard 10 andsupporting theauxiliary or secondary standard 1 1.

The standard 14 carries a block 8 on which the resilient throw offfinger 6, is mounted, the block 8 bein designed for a limited upwardyielding motion by virtue of the slot 7, pin 22, spring 13, and abutmentpin 23.

15 designates a roller which is mounted at 16 to the bracket 17, whichis adjustably secured at 18, on the standard 10, so as to be susceptibleof being located in diiferent horizontal planes.

19 is a guard which is pivoted at 20 to the bracket 17, andis held inposition by a stop 21, the guard 19 being susceptible of yieldingupwardly when necessary.

25 is the shoe which is adjustably secured at 26 to the standard 10, andthe shoe 25 cooperates with the finger 6 to the extent of compressingsuch finger or moving it out of the path until the board has passed theshoe, whereupon the finger 6 will throw the board over into thereceptacle provided for it, as indicated in Figs. 1 and 6 of thedrawmgs;

In operation, the boards are passed along the machine through the throwoff devices as indicated in Fig. 1. Boards of a width less than thedistance between the chain 4L and the underside of the guard 19, and ofgreater width than the distance between the chain a and the underside ofthe shoe 25, will be engaged by the spring finger 6 as they pass the end24: of the shoe 25 and be thrown out into the receptacle provided forthe purpose, as best indicated in Fig. l of the dr wings. Boards ofother sizes will pass through the particular throw out de vice and bethrown out by a subsequent throw out device which has been set for theboard of the particular size.

From the foregoing description taken in connection with the accompanyingdraiving, it is thought the complete construction, operation andadvantages of the invention will apparent to those skilled in the art towhich it relates.

What I claim is 1. In a board assertin machine, the combination with theconveyor that conveys the boards along and the fence inst which theboards lie, of selective throwing out mechanism which comprises astandard, a roller carrying bracket vertically adjustable on saidstandard, a secondary standard adjust-ably carried by said primarystandard, and a resilient throw out finger carried by said secondarystandard, substantially as show and described.

2. in a throw out device for board assorting machines and the like, aprimary standard, guard nieinbcr carried by said standard, a seccaidarystandard supported from said primary standard, a resilient throw offfinger carried by said secondary stai'idard, and a shoe on said primarystandard eoop erative with said finger.

3. In. a throw out device for board assorting machines and the like, aprimary standard, a guard member carried by said stand.- ard, asecondary standard supported from said primary standard, a resilientthrow oil finger carried by said secondary standard, and a shoe on saidprimary standard cooperative with said finger, means for yieldablysupporting said guard member on said standard, and m ans for yieldablysupporting said throw out finger on said secondary standard.

4. Throw ofif devices for board assorting machines and the like,comprising a vertical standard, a roller carrying bracket verticallyslidably mounted on said standard, means for holding said bracket inposition on said standard, a secondary standard, an adjustable elainpbracket connection between said standards for supporting said secondarystandard from said primary standard, a resilient throw oil fingercarried by said secondary standard, a shoe carried by said primarystandard to cooperate with said finger and projecting a lesser d ancethan the proje tion of said finger, whereby when a board passes betweensaid shoe and finger, said finger will tend to throw oil said board whenit passes the shoe, and means for restraining the action of said fin erif the board he of a greater than the predetermined size for which thethrow oil mechanism is adji ted to operate.

'lhrow oil devices for board asserting machines and the like, comprisinga vertical standard, a roller carrying bracket vertically slidablymounted on said standard, means for holding said bracket in position onsaid standard, SQCOndttl'jf standard, an adjustable clainp bracketconnection between said standards for supporting said secondary standardfrom said primary standard, a resilient throw off finger carried by saidsecoi'idary standard, a shoe carried by said primary standard tocooperatewith said finger and projecting a lesser distance than thePI'OJGCiLlOll of said finger, whereby when a board passes between saidshoe and finger,

said finger will tend to throw ofif'said board when it passes the shoe,and means for restraining the action of said finger if the board he of agreater than. the predetermined size for which the throw off mechanismis adjusted to operate.
